A patient receiving mechanical ventilation is being continuously monitored for oxygen saturation measured by pulse oximeter (SₚO₂)for the past 48 hours.When initially applied,the SₚO₂ and the arterial oxygen saturation (SₐO₂),as well as the pulse on the pulse oximeter,ECG,and manual pulse,were consistent.During clinical rounds,the respiratory therapist notices that although the probe is appropriately placed and capillary refill is normal,the SₚO₂ reading is down to 90% from 95%.The most appropriate immediate action is to do which of the following?
A) Replace the probe.
B) Reposition the patient.
C) Draw an arterial blood gas.
D) Move the probe to a different site.
